Be it known t L Jones ll. i citizen-o tlieUniteal States of Arneriemom residing at Smells, in eourny of "Dori and State of TTebraslm, have invent tein new and useful linproieinen s ll filer-Bearings of which the following is n specification, such as will enable those skilled in the art to which opgertains to make and use the some. v The object this invenlizmv is to pro vide a self-contained be: king mleptecl to take both radial and end-thrust loads upon rollers, as distinguished from bearings in which balls are sell to take both such low s, and also from those employing conical rolladnpted primarily to tel-'9 radial load but being also subjected lo earl-thrust load both of \\'l forms have been found. be

20 very shor 'ed.

This invention is distinguished over z oo pending application in the feet that 1 91'0" 'vide two beveled flanges on the rollers of the present form, preferably at or adj cent the roller ends and adapted to sale the encltlirnst in eitherxlireotion without reelneing' the .eifeoiive retrial lom'l eemcity of the rollers. i

The presentlorm is still further (lis guisliecl by feet that l employ solio Lu bearing members insteacl of she built-op members shown in ilie ssicl application.

A still further distinguishing featursides in the fact that my presses beeringgs are open at the ends and shes permit e egress of any metal cuttings due to excessive end-thrust loscl, well as so on sign or other cleleterious matter I might be in or $633k bearings; and :1 still further difference is that 1 only flange one half slie rollers in the present iorin films obtaining more radial load eopeL'L because of the rollrs not flung-eel oml wi u out loss of en ltlirnst load capacity "for the reason that 1 en ploy the some nnmlier of flanges in the as a Whole and, in the present fornn izlie pintles on the flanged rollers. are considerably larger in dis 'tlmn filiose oi the unfiengecl rollers films enabling me to employ two more bells for each pintle of the flanged rollers which mm serially siol in maintaining the elinement thereof.

My invention is fully see Io his in lowing speoilicaiion, e osnying rewin form pore Wl Specification of Letters lParten 3W of a h aring conr my presens inxterior 'elevaeion, pr 1' A line zr-u 11ml parfly on the line g,/;; of 2'; anal Fig 2 is a section taken on .16 line 22 of 1. lo the firswin f s forming a port of this :ioplieosion l-lim shown a cage comprising en-plsites a one ioizo rl by ribs of, said notes and; ribs locked together by means of ri ets (1 or suitable equivzilent, and sol l recessed, as shown of zintifriction being preferably 's and end- ".3 is im mactieable esirel positions. \cl. between the Vll reasons lojier exlers are provided icli the correspondmore or i insiotoce, by the endei 't or n'lieol when my been in nuromolsile \r ieels and. reporting portions of 2 Y W, 7 rectory assembleo, .;y of faulty or of derangelik some oegree es es Z1 whereveen. for

ber f is similarly provided with an outwardly directed, cylindrical, portion having shoulders f of the same inclination as the flanges 5 these members being preferably of a single piece each, andit Will be seen that the end-thrust is taken by the flanges at one end of the rollers, on the inner beveled faces thereof, through the rollers, and

by the inner beveled faces of the flanges at .when solid bearing members 6 and f are used, said assembling being accomplished by placing the member f within the member 6 in the position of the greatest eccentricity or, in other words, by having the members approximately touch each other, in which positions a space is provided. therebetween for the passage of the flanges b of the rollers b and, when these rollers are in position between the members, they may be spaced by being moved about the inner member which thereby assumes a position of concentricity with respect to the member a. The rollers Z) are then arranged in their respective cups a, of one of the cage end-plates, after which the rollers are arranged between the rollers I), the other end-plate placed in position and the cage rivets or other securing means being then employed to .lock' the cage elements together, thus locking the bearing members e and f in position as well, and my hearing, as a unit, is ready for handling, shipment, or installation, without danger of displacement of any of the parts. i

It will thus be seen that I provide a bearr ing in which a line contact is insured for both the radial and end-thrust loads, as distinguished from the point contact of a ball bearing, and the very destructive friction in a conical roller bearing taking both loads is avoided, thus insuring a bearing, for combined radial and end-thrust loads, of high elliciency and of great permanence and durability, and any tendency of the rollers to get out of alinement is prevented anti-frictionally, thus also insuring the bearing against wear.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. A bearing, comprising an outer solid ring having a centrally arranged, inwardly directed, member presenting a cylindrical bearing surface, an inner solid ring having a centrally arranged, outwardly directed, member presenting a cylindrical bearing surface, a plurality of cylindrical rollers operating on said bearing surfaces and provided,

each, with end flanges of greater diameterthan said rollers impinging on corresponding edges of said members to take end thrust,

presenting a cylindrical bearing surface,-an

.55 3. A bearing, comprising an outerflsolid ring having an inwardly directed member inner solid ring having an outwardly 'di-" Y rected member presenting a cylindrical bearing surface, said rings being outwardly flared from said members to permit the escape of foreign matter, a plurality of rollers operating on said surfaces and provided,

each, with end flanges impinging on corre-' sponding edges of said members to take end thrust, a plurality of unflanged rollers, and means for guiding said rollers.

In testimony that I claim the foregoing as my invention I have signed my name in pres ence of the subscribing witnesses this 5th day of December 191 v JULIUS AUGUSTUS PERKINS.
